Our modern diets have much too much omega-6 (bad), and far too little omega-3 (good).
The normal supplements don’t fix a deficiency that is several years old. Mega doses of highly purified stuff will make a big difference in a few weeks.
[See Omegabrite.com (No, I don’t have a $$$ interest. My son completely changed his focus and mood with Omega-3 and nothing else.)]
There is SOMETHING to the Omega 3s and brain development, that is for sure. My non-talking (and not autistic) son started taking high quality fish oil supplements (they are NOT all alike and some risk mercury poisoning so be CHOOSY - go to your health food store and get the best) and within two weeks he began to speak.
Now we all add crushed flax seed to cereal or shakes, and take the fish oil supplements too.
Do you have any source on this other than the seller?
